Calatheas are widely grown for their decorative foliage and generally prefer warm, humid conditions with bright indirect light. Many plants sold as calatheas are now botanically classified under related genera such as Goeppertia.
Growing Tips
- Use a clean, fine-textured seed-starting medium that drains well while retaining moisture.
- Keep newly sown seeds warm, humid, and consistently moist without making the medium soggy.
- Provide bright filtered light and protect young seedlings from strong direct sunlight.
- Handle seedlings gently during transplanting because young roots can be delicate.
Seed Storage
Store unused seeds in a cool, dry place away from direct sunlight and moisture. Keep them in a tightly sealed seed packet or airtight container. Avoid areas exposed to heat, humidity, or frequent temperature changes.
Unique Facts About Seeds
- Calatheas are commonly known as prayer plants because their leaves can move upward at night, a behavior called nyctinasty.
- The plants are members of the Marantaceae family, which includes several attractive tropical foliage plants.
- Many plants traditionally called Calathea have been reclassified into the genus Goeppertia.
- Calatheas are primarily appreciated for their patterned foliage rather than their flowers, although some species can produce attractive blooms.
